Answer:

y = 1x - 40

Step-by-step explanation:

Find the slope first which is the rise/run. And then you get the slope which is 1, and the slope intercept form is y = mx + b. Your y intercept is -40 so when you plug them in it makes y =  1x - 40

Answer:

218.75

Step-by-step explanation:

218.75

140/x=64/100

Answer: 218.75

Explanation:

64/100*x is equal to 64x/100 = 140

14000 divided by 64

x = 218.75

3500=700 \times 2 ^ { 8x }

\frac{3500}{700}=2^{8x}

5=2^{8x}

2^{8x}=5

\log(2^{8x})=\log(5)

8x\log(2)=\log(5)

8x=\frac{\log(5)}{\log(2)}

8x=\log_{2}\left(5\right)

x=\frac{\log_{2}\left(5\right)}{8}

[tex]\text{The \textbf{value} of x is\ } \dfrac{\log(5)}{8\og(2)} \ \text{and} \dfrac{\ln(5)}{8\ln(2)} \text{\ for the \textbf{equation},}\ 3500=700\times 2^{8x}.[/tex]

So, option c) and d) are correct.

Logs with base a, they are called Common Logs and Logs with base e are called Natural Logs.

[tex]\text {Thus,x=\dfrac{\log(5)}{8\log(2)} and}[/tex]

Given equation:

[tex]3500=700\times 2^{8x}\\[/tex]

In order to solve it for x first take logarithm both sides of the equation as follows:

We can take log natural as well as common log

1. taking common log:

[tex]log(3500)=log(700\times 2^{8x})\\log(3500)=log(700)+log( 2^{8x})\\log(3500)-log(700)=8x\ log( 2)\\\\log\dfrac{3500}{700}=8x\ log( 2)\\\\log5=8x\ log2[/tex]

Evaluating x as follows:

[tex]x=\dfrac{\log(5)}{8\log(2)}[/tex]

2. Similarly on taking natural log:

[tex]x=\dfrac{\ln(5)}{8\ln(2)}[/tex]

[tex]\text{Thus, the \textbf{value} of x is\ } \dfrac{\log(5)}{8\og(2)} \ \text{and} \dfrac{\ln(5)}{8\ln(2)}[/tex][tex]\text {Thus,x=\dfrac{\log(5)}{8\log(2)} and}[/tex]

So, option c) and d) are correct.

[tex]Q=(9,11)[/tex]

Step-by-step explanation:

Solving (4a)

[tex]P (x_1,y_1) = (1,1)[/tex]

[tex]M (x,y) = (5,6)[/tex]

Required

Determine [tex]Q(x_2,y_2)[/tex]

To do this, we make use of the mid-point formula:

[tex]M(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Substitute values for x, y, x1 and y1

[tex](5,6) = (\frac{1+x_2}{2},\frac{1+y_2}{2})[/tex]

Multiply through by 2

[tex]2 * (5,6) = (\frac{1+x_2}{2},\frac{1+y_2}{2}) * 2[/tex]

[tex](10,12) = (1+x_2,1+y_2)[/tex]

By comparison:

[tex]10 = 1 + x_2[/tex]

[tex]x_2 = 10 - 1[/tex]

[tex]x_2 = 9[/tex]

[tex]12 = 1 + y_2[/tex]

[tex]y_2 = 12 - 1[/tex]

[tex]y_2 = 11[/tex]

Hence, the coordinates of Q is (9,11)

Answer:

V/3r²

Step-by-step explanation:

We are to make h the subject of the formula as shown;

V = 3r²h

Divide both sides by 3r²

V/3r² = 3r²h/3r²

V/3r²  = h

Rearrange

h = V/3r²

Hence the formula to calculate the height h is V/3r²

Answer:

h = V/3r²
